Photovoltaic DC switches are DC switch devices specially designed for photovoltaic power generation systems. They are mainly used to switch, control and protect photovoltaic modules, inverters and other DC loads. In photovoltaic systems, photovoltaic DC switches play a vital role to ensure the safe and efficient operation of the system.
The critical role of multilevel inverters, particularly Voltage Source Inverters, in the efficient integration and transmission of solar energy into the electrical grid is evident from the challenges and system application needs discussed.
Moreover, the inverters are interconnected in parallel with PV cells, facilitating power conversion in a singular-stage configuration. In the traditional structure of solar power plants, inverters and low-frequency transformers are utilized as an interface between PV panels and the AC grid for power transmission.
To manage the multiple voltage levels and reduce switching losses, multilevel inverters often rely on advanced control techniques such as MPC and SVPWM. These control methods, while effective in optimizing inverter performance, add computational demands and can introduce latency, potentially impacting system reliability.
By directly controlling the switching sequence in inverters, this method is responsible for controlling the output waveforms of current and voltage. Inverter performance is determined by managing and controlling switching losses and fluctuations, facilitating efficient operation according to the switching device's requirements.
A novel transformerless five-level inverter, structured upon the FC topology, has been introduced for utilization in PV grid-connected systems .
